Madonna reportedly turned down the chance to perform a duet with Stacey Solomon on Saturday night's X Factor.

According to The Sun, the pop superstar had been in talks to team up with Dannii Minogue's act for the final, but her team eventually rejected the offer because she does not have new material or a tour to promote.

A source said: "We were told she wasn't in promotion so it wasn't going to happen. It's a shame as she'd have been brilliant and given the show a real lift, especially with Stacey."
